The bayonet 19 is connected to the inner wall of the pin hole in the iron sleeve 15 through a spring 20. A cone is provided on the other side of the iron sleeve 15, and the other side of the slide groove 13 A bayonet is provided on the inner wall of the bracket 17, one end of the clamping cone 17 is clamped in the inner side of the bayonet, and the other end of the clamping cone 17 extends to the inner side of the cone mouth, and one end of the clamping cone 17 is connected to the inner wall of the bayonet through a spring three 18. When the LED display screen 3 and the bracket 2 are overturned due to a strong impact, the roller 5 compresses the spring one 6 under the pressure of the base 1, and the roller 5 is squeezed to the button 12. The button 12 turns on the electromagnet 14 on the same side. The electromagnet 14 is energized to generate magnetic force, and the clamping cone 17 is stretched by the magnetic force. The spring three 18 is further pulled to the inner side of the iron sleeve 15, and the roller 5 is pressed to the button 12. The clamping cone 17 fixes the iron sleeve 15 and the electromagnet 14 on the inner side of the slide groove 13 in the bracket 2. At the same time, the suction force of the electromagnet 14 compresses the spring 20 of the clamping pin 19 and moves it out from the inner side of the movable plate 22, so that the electromagnet 14 is separated from the movable plate 22.

The motor 9 drives the screw rod 10 to rotate, and the screw rod 10 pushes the bottom plate 7 downward through the threaded hole 11, so that the bottom plate 7 moves downward and squeezes the suction cup 8 on the ground, and then is fixed to the ground by the suction cup 8, which is convenient for quickly moving and fixing the LED display screen 3. The LED display screen 3 is effectively fixed through the base 1 and the bracket 2 to avoid the LED display screen 3 from moving or even falling due to being touched, thereby ensuring the safety of the LED display screen 3. When the LED display screen 3 and the bracket 2 are tilted due to a strong impact, the roller 5 compresses the spring 6 under the pressure of the base 1, and the roller 5 is squeezed to the button 12, and the button 12 opens the electromagnet 14 on the same side. The electromagnet 14 is energized to generate magnetic force, and the clamping cone 17 is stretched by the magnetic force to lengthen the spring three 18 and further pull it to the inside of the iron sleeve 15. The clamping cone 17 is used to fix the iron sleeve 15 and the electromagnet 14 to the inside of the slide groove 13 in the bracket 2. At the same time, the suction force of the electromagnet 14 compresses the spring four 20 of the clamping pin 19 and moves it out from the inside of the movable plate 22, so that the electromagnet 14 is separated from the movable plate 22. The energized electromagnet 14 attracts the iron sleeve 15 on the other electromagnet 14 by magnetic force, and the iron sleeve 15 drives the movable plate 22 to move in the direction of the bracket 2 tilting, thereby effectively utilizing the movable plate 22 to land first, and the suction force of the electromagnet 14 is used for buffering, effectively avoiding the bracket 2 and the LED display screen 3 from directly hitting the ground, thereby protecting the safety of the LED display screen 3.
